GEORGE ST. JOHN, OF HEMPSTEAD, NEW YORK.

WEATHER- STRIP.

Application filed April 19, 1915.

To all whom it may concern:

Be it known that I, GEORGE ST. JOHN, a citizen of the United States, and a resident of Hempstead, in the county of Queens and State of New York, have invented certain new and useful Improvements in IVeather Strips, of which the following is a full, clear, and exact specification.

The object of this invention is the con struction of improved means for rendering weather-proof the lower edges and the lower section of the lateral edges, of a door, window sash and the like.

Referring to the drawings forming part of this specification, Figure 1 is a front sectional elevation of the lower portion of a door having a weather strip applied thereto which embodies my improvements. Fig. 2 is a horizontal section of the same. Fig. 3 is a vertical transverse section.

In the drawings, the reference numeral 1 designates the door to which my weather strip is applied; 2, the door jambs, and 8, the door sill. In the bottom edge of the door is a deep slot 4 within which are two L-shaped strips 5, preferably of metal, and slidably held together by small bolts 6 rigid with one strip and loosely held in the slots 7 of the other strip, so that by sliding the strips 5 somewhat apart they will present their branches 9 against the door jambs 2, while resting upon the sill 3.

For causing the strips 5 automatically to press their branches 9 against the door jambs as the strips descend by gravity to the door sill, each strip is given an oblique slot 10 within which loosely fits a fixed pin 11, so that it cannot descend without the desired lateral movement, nor be raised without drawing inward said branches.

For enabling the strips to be raised, two bell-crank levers 12 fulcrumed on a fixed pin 13, have their lower arms slotted, and have such slots loosely engage pins or studs 14 projecting from the strips, one lever engaging one stud; and the other lever, the other stud. From the substantially horizontal arms rise links 15 to a yoke 16 supported by the pedals 17 17 pivoted at 19, 19. By pressing ones foot down upon the outer end of the pedal 17 or 17 said yoke and links are elevated and the levers 12 are caused to Specification of Letters Patent.

draw the two weather strips 5 inward. When thus drawn inward, the action of the fixed pins 11 upon the oblique slots 10 causes said strips to rise until they are clear of the door sill 3. The door is now free to be swung open.

To insure the air-tight closure of the weather strips 5, I prefer to fasten to the surfaces of the door jamb 2 and sill 3 a ribbon of some yielding material, 20, as of lead, felt and the like. Lead is preferable because of its retention of the groove or indentation made therein by the edges of the weather strips, whereas felt is more resilient.

To add to the appearances of the door and fill the otherwise open space beneath its lower outer edge, I hinge to the latter a narrow length of brass tape 21, the hinges being along the top edge of said tape, and provide springs 22 for normally insuring a vertical position of the tape or narrow plate 21. While such plate or drop-leaf can easily yield when the door 1 swings over the sill, yet its springs cause it immediately to return to its vertical position when the door reaches its closed position, and thereby fills the crack otherwise showing beneath the door.

In opening the door, the person first presses his foot upon the pedal 17; then turns the knob and pulls the door open; in closing it, the inclined surface of the sill 3 meets the weather strips and wedges them upward until they pass it.

What I claim is:

1. The combination with a door and the like, having suitable grooves or slots therein, of two horizontal overlapping strips movable in said slots, each stri having a vertical branch at its outer en means holding the overlapping ends in alinement but relatively slidable, each strip having an oblique slot, a fixed pin in each slot, and means operative exterior to the door for elevating said strips and connected branches, said oblique slots and fixed pins serving to cause the in-drawing of the strips simultaneously with their elevation.

2. The combination with a door and the like having a slot in its lower edge, of two horizontal overlapping strips slidable in said slot, one strip having two horizontal slots in its overlapping section, and the other strip having projections loosely entering said slots, each strip having an oblique slot, fixed pins entering the last-named slots bell-crank levers pivotally supported by the door, and a pedal fulcrumed in the door and connected with said levers to force their lower ends inward when the pedal is depressed, each of said levers being connected at its lower end with one of said strips. 10

In testimony that I claim the foregoing invention, I have hereunto set my hand this 5th day of April, 1915.
